96 Core Optical Fiber Composite Ground Wire Aerial Stranded Aluminum Clad Steel Single Mode Opgw Cable
Description:
Optical Fiber Composite Overhead Ground wire (OPGW) is a type of cable that is used in overhead power lines. Such cable combines the functions of grounding and communications.
An OPGW cable contains a tubular structure with one or more optical fibers in it, surrounded by layers of steel and aluminum wire.It is mainly used for communication lines of 110kV, 220kV, 500kV, 750kV and new overhead high-voltage transmission systems. It also can be used to replace the existing ground wire of the old overhead high-voltage transmission system.
The OPGW cable is run between the tops of high-voltage electricity pylons. The conductive part of the cable serves to bond adjacent towers to earth ground, and shields the high-voltage conductors from lightning strikes. Special structures can be customized according to user needs.
Applications:
1. aerial ground wires
2. Power line communication systems
Feature:
1. High quality standards for designing, testing and producing with grade A materials available to ensure long-term reliability.
2. Engineering support supervising and providing its own line of accessories hardware.
3. Seal stainless steel tube superior protection to the fiber optical to moisture and extreme environmental
conditions such as lightening.
4. To construct OPGW must cut power, resulting in greater loss, thus OPGW must be used in constructing high pressure line over 110KV.
5. Apply to the transformation of old lines.
Layer stranding structure:
1. Big diameter and more optical fiber.
2. Big tensile strength and short-circuit capacity,arrive the best balance of machanical and electrical properties.
3. One or more optical unit.
4. Best design of stranding,obtain secondary optical fiber extra length.
5. Strands piles can be two or three,the wire can be ACS wire and/or the combination of aluminium alloy wire and aluminium wire.
